What's the SLOWEST machine you're running BOINC on? Something that's crunching daily, not a part time thing or something that you used to crunch one workunit on 9 years ago. Something current. A link to it is going to be required, I'm afraid.

An old laptop, Compact/Tosiba, 1995, 133Mzh processor that I intend to get back up and running again 24/7 if possible. Not sure if will use it for SETI or Einstein. Also, an iBook, (2003) will be used and will ask my better 7/8s if I can use her eMachine (2002)-1.8 Mzh processor, also. Split up SETI/Einstein among the four. The sloth machines may do more than I expect if they run 24/7...maybe?

Didn't Astro of a while ago have a most excellent thread on his adventures with an old P90 CPU...!

Actually, it was a P60, the first generation Pentium ever released.

That would be a most worthy winner... er, I mean looser... ummmmmmm. To be frank I'm unsure what I mean but a P60? That's just BRILLIANT.

Seeing as were talking unused machines now, I DID have a Performa 400 running the old SETI@Home client back when. 16MHz of screaming Motorola 68030 POWER that was!

Had a 80486DX66, with a VESA Local BUS system, a (VESA) SCSI-card, half the size off the MoBo, with 8MByte RAM!. Unfortenatly the SCSI-card is broken. These 486 didn't even have cooling problems ;)
Worked with EXpanded or EXtended memory and the Disk Operating System 4.01 (D.O.S.).

16MHz? I could do one and only one better, 1.79MHz and that was an Atari 1200XL computer which I have now, But It's awaiting a new motherboard and psu brick which should cost Me w/shipping $60.68 total, Would It run Seti? Not likely at this stage as I'd need a C compiler and I'd have to configure Seti to do what Seti Classic did and yet support Boinc and in a limited memory envelope of 64K to 512K or even as much as 1024K, As hdd capacity or access to a hdd isn't a problem, Internet would have to be via dialup as the 1200XL has no ethernet capability. Somebody must have something slower, somewhere.Pluto is still a planetBeep! Beep!

The Via C3 and C7 are very interesting processors. The integer speed is almost triple, which I'd expect, and the floating point performance is about the same even though the C3 is running at a 4 times higher clock.

The nice thing about the C3 is that they're very low power. I haven't got a C3 based machine over 35 watts total, and I have one under 20 watts.

I have a few "slow but steady" crunchers in my midst. Hey, they were just sitting there doing nothing anyways. Yeah, they are slow and are not as "efficient" as my newer rigs, but what the heck, now they are "doing" something whilst sitting, and also......I don't pay the electric bill!
